VirtualBox can be installed in Ubuntu very comfortable way and it always works -
http://www.virtualbox.org/wiki/Linux_Downloads - there is repo for ubuntu and other Debian based
distros to install it through APT. VM Ware Server has also repo but it is not updated very
frequently and also VM Ware Server development itself is quite slow. VirtualBox has much faster
development. Probably VM Ware is developing more those commercial versions and free VM Ware Server
version is not in focus.
For VM Ware and Linux, especially Ubuntu, you can search from Google. Here is one article for
reading to get picture - http://howtoforge.com/vmware-server-on-ubuntu8.04
This patching script doesn't work always... And if you renew your kernel, then this action needs to
be repeated. using VirtualBox it works flawlessly - after kernel update and restart just run sudo
/etc/init.d/vboxdrv setup to recompile new kernel modules and it always succeeded.
After restart make sure you use newly installed kernel. At /boot/grub/menu.lst there is useful to
have some conf:
## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=true
If you need just one kernel at your boot list, then change this at /boot/grub/menu.lst:
## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=1
There are some prebuilt VM Ware modules for Linux:
http://www.vmware.com/support/reference/linux/prebuilt_modules_linux.html
VM Ware has true BIOS simulator, VirtualBox doesn't have this. VM Ware Workstation has even virtual
machine session capture feature into videofile. But using VirtualBox and recordMyDesktop can do
same. I've done this many times using VirtualBox and recordMyDesktop.
VirtualBox works faster than VM Ware. Free VM Ware Server does not have shared folders feature.
VirtualBox have this.
Under Linux you need some tweaks to get work USB but it can be done by adding few lines into conf
file(s) and it works well. Also USB 2.0 works under VirtualBox. In OSE (OpenSource Edition) there
are some missed features - http://www.virtualbox.org/wiki/Editions
So, I need usually full version.
Look here for USB support at VirtualBox under Linux:
http://michael-prokop.at/blog/2007/07/11/virtualbox-usb/http://ubuntuforums.org/archive/index.php/t-551469.html
Certainly, you can Google for more instructions. But at first look you VirtualBox installation -
there can be this USB alread work and you don't need add those tweaks.
I used:
# close VirtualBox if it was opened
# sudo nano /etc/init.d/mountdevsubfs.sh
# approx 40. row ("Magic to make /proc/bus/usb work") remove # from following 4 rows:
mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb
# you can set here also devmode=644, then probably you don't need to add those two lines below into
/etc/rc.local
# save (F3) and quit (F2)
# sudo /etc/init.d/mountdevsubfs.sh stop
# sudo /etc/init.d/mountdevsubfs.sh start
# sudo /etc/init.d/vboxdrv reload
Also I added following two lines into /etc/rc.local :
VBOX=$(grep vboxusers /etc/group | sed 's/vboxusers:x:\(.*\):.*/\1/')
mount -t usbfs -o devgid=$VBOX,devmode=664,nodev,noexec,nosuid none /proc/bus/usb
Note that in /etc/rc.local there must be the word "exit 0" always the last and always at least one
empty row at the end.
Then my USB support works flawlessly under Linux and VirtualBox. When I assign USB-stick into
virtualmachine in configuration dialog, then when I plug in that USB-stick - it will directly work
under virtual machine.
VirtualBox 2.1.4 has also experimental 3D support. In VM Ware Server I tweaked some conf files to
get it work but it wasn't stable - next restart and 3D support was lost under VM Ware Server.
VirtualBox 3D support seems to be more stable. More reading about VM Ware 3D support -
http://www.vmware.com/support/ws55/doc/ws_vidsound_d3d_enabling_vm.html
I've used VM Ware Workstation under Linux and Windows several years but now I use VirtualBox,
because it works faster and frequent updates are coming - development is at good level. Also
VirtualBox installation especially under Linux works much-much better than VM Ware installation.
VM Ware Server kernel modules are buggy for Linux and it's real pain to get it work. You need to
patch VM Ware modules and recompile and repack them again, etc. For that you need build-essential
package and also kernel headers, which adds tons of new packages to your system, which you normally
don't need. VirtualBox installation over APT works flawlessly and also kernel modules are compiled
very easily and always succeeded. This reason has been main reason why I took VirtualBox and use it now.
Perhaps under windows there is VM Ware Server easier to install and there is no big difference but
VirtualBox is lightweight and works faster for me, especially switching between full screen and
windowed mode.
VM Ware Server needs registration at VM Ware webpage to get free licence keys to install. VirtualBox
has no licence keys and you can install it right now.
So, VirtualBox has quite much advantages against free VM Ware Server and VirtualBox is also
completely free and there is also OpenSource Edition of VirtualBox available. VM Ware doesn't give
almost any source out, if then some small kernel modules.
But as always - it depends all your needs. E.g. VM Ware Server allows to boot operatings systems
over internet - you can log in as regular user to the Windows PC and run virtual maschine installed
in there over internet in your PC. I think it should work also under Linux but never tested. It was
damn slow and has no point, perhaps in internal network.
